Kristen Stewart arrived back in the United States just in time for Independence day, but she sure didn’t look like she wants to celebrate. Do you think she looks sad because Rob is now dating Riley Keough?

WhenKristen Stewart jetted back into LA’s LAX airport on July 4 after her whirlwind trip to Paris, she looked a little down in the dumps. Sure, she could just be tired from travelling, or was it that she was upset that she was back in LA, where her ex Robert Pattinson has been seen out driving with his new love and Kristen’s former co-star Riley Keough?

Kristen Stewart Looks Sad Arriving In LA

When Kristen, 23, landed back in LA on July 4, she was rocking a white tank top and jeans. But she looked pretty sad, and we can’t help but think she is nervous that she will have to face the fact that her ex boyfriend of nearly five years is now dating someone else. We know that we’d feel that way.

Kristen Stewart Is ‘Livid’ That Rob Is Dating Riley

“Kristen feels that she acted as mentor to Riley on her first film The Runaways, introduced her to Rob and encouraged her to make a career of acting,” a source told the Daily Mail. “Kristen is emotionally volatile at best of times and flew off the handle when she found out about Rob’s liaison with Riley.”

Kristen even invited Riley to her April birthday party, and she has let Rob know she is devastated that he is now dating her friend.

“Rob has been made aware through friends that she is devastated,” the Daily Mail source says. “She’s told Rob via friends she feels violated.”

Despite the fact that Riley’s rep has said that Riley and Rob aren’t dating, Hollywoodlife.com spoke to sources close to the pair, and they have re-confirmed to us that they are seeing each other. In fact, the reason Rob likes Riley so much is because she is so down to earth.

“[Rob] really likes the fact that [Riley] is not absorbed by celebrity and that she really isn’t a celebrity herself. Her family members are the celebrities. Basically [Riley] can walk into stores and nobody really knows who she is — she and Rob bond over the fact that their lives together are more normal. His relationship with Kristen, however, felt like a Ben Affleck & J.Lo situation. It was too much of a show. Riley is a cool girl that lets Rob be himself,” a source told HollywoodLife.com exclusively.

Furthermore, sources close to the couple reconfirmed to the Daily Mail that they are seeing each other.

Let’s hope she doesn’t bump into them in Los Feliz!
